BGE collision bounds script
The __name__ and __main__ are as they should be. You do not need to put anything in the underlined places.

__name__ is a variable that either contains the name of the script or the string "__main__" if you run the code in script mode. Again, you don't need to touch them.



I doubt this script will help your issue though. You probably need to look at how to set up a proper character system in BGE. Armatures don't do physics.
